They enhance the visibility of the wearer at night or in low-light conditions when illuminated by vehicle headlights.

They consist of highly retro-reflective microprisms formed on a flexible, glossy, UV-stabilized polymeric film.

A flexible vinyl film seals the front and back of the material, encapsulates the microprisms, and protects the reflective surface from dirt and moisture penetration. Fluorescent red-orange and fluorescent lime-yellow colors are conspicuous under daytime conditions, particularly at dawn or dusk and or cloudy days.

They maintain their reflectivity through repeated launderings and are supple, durable, and are easily wiped clean of oil, coal dust, dirt and grime.
